Just a small correction as regards my interest in the Studiologic. I am not looking for a cheap MIDI controller but rather for a budget replacement/addition in the field of piano sounds. At present I have the PA800 and ketron SD1plus as well as the old Yamaha P80 stage piano. The latter has (for me ) a phenomenal keyboard action and strangely the sound thru my simple small Creative T10 speakers is also impressive. Unfortunately once you start recording the sound it loses out big time. I have just finished completing a full CD only playing the Yamaha P80 ( as a beginner really as I set out to play the piano in 2015) and am pleased with the result though in all fairness the result would have been better of course had I been able to record all that with the high end pianos mentioned in this thread. By the time I can afford to splash out a wack of money for a decent stage piano I will definitely bear in mind the Roland RD2000, as well as the Yamahas such as the CP40 and CP4 and of course the Nord.
Incidentally I just uploaded my piano CD for a friend of mine so if any are you are curious what a beginner at the age of 65 with a piano with a sample memory of 13 Mb ( yes megabyte!!!) can sound like, feel free. ( CD covers with content included):
